Description
Technical field
The present invention relates to the vegetables oil is the transformer oil preparation method of raw material.
Background technology
Transformer oil is important liquid insulating medium, in electrical equipments such as X-former, uses in a large number.Because mineral insulating oil is with low cost, insulating property and cooling performance are good, in the electrical equipment manufacturing, are used widely.But the biodegradable of mineral insulating oil is poor, in case serious leakage will cause severe contamination to soil, water source and even public community on every side; And the burning-point of mineral insulating oil is low, and is high temperature resistant and fire resistance is poor, is not suitable in the mine, mine, military installations, Highrise buildings etc. are to using in the high place of fire-fighting safety requirements; The reserves of natural oil are limited simultaneously, estimate serious oil shortage will occur in the middle of this century.
In order to satisfy the demand to high burning-point liquid insulating material, the work of seeking high-temperature behavior good insulation performance oil is the direction that people study always.Not fuel oil of Askarel has been invented by nineteen twenty-nine Britain Si Wang company, and its staple is polychlorinated biphenyl (PCB).PCB has very high chemicalstability and electric insulation intensity, and is poisonous but late 1960s it is found that PCB, and various countries all prohibite and use and sell afterwards.Substituting in the oily process of searching PCB, number of research projects has been done by various countries manufacturer.The 1950's, silicone oil was invented by the U.S., but just came out up to first transformer silicon oil in 1974.Britain GEC company had made first X-former with the synthetic ester of the Midel7131 of difficult combustion in 1977.The beginning of the eighties, Britain developed not fuel oil of Formel, and nineteen eighty-three, first X-former put into operation.U.S. DSI company has developed the petroleum-type fire resistant oil in recent years successively, has wherein that α oil, β are oily, a polyalphaolefin etc.
Fuel oil and fire resistant oil do not grow up because of transformer oil fire resistance difference; The seventies is in the process that substitutes oil product of seeking X-former; People require with being not less than 300 ℃ with the burning-point that has, and this index table doubles above than transformer oil and is widely accepted.All more than 300 ℃, each item performance and transformer oil are suitable for the burning-point of these composite insulations, but cost is too high, therefore are very limited in the use.
Publication number is that the Chinese invention patent Shen Qing Publication specification sheets of CN101230304A discloses a kind of environment-friendly type transformer oil and preparation method thereof; With vegetables oil and tankage thereof is raw material, through alkali refining, dehydration, esterification alcoholysis, stop neutralization, washing exquisiteness, underpressure distillation, decolorization filtering and 0.1-5.0wt% oxidation inhibitor is gone in blending, the 0.1-5.0wt% pour point depressant makes.But publication number be the flash-point of environment-friendly type transformer oil of CN101230304A about 215 ℃, can not reach requirement as difficult burning-point oil, limited its application in high fire resistance place.Secondly, the antioxidative stabilizer of this environment-friendly type transformer oil is still waiting further raising.
